Technology Overview

Super DLTtape continues to build on generations of DLTtape success while ensuring compatibility with previous DLTtape formats. Super DLTtape systems offer significantly improved throughput and capacity by using industry leading magnetic tape technology advances.

Laser Guided Magnetic Recording
Based on Quantum-developed Laser Guided Magnetic Recording (LGMR) technology, Super DLTtape incor-porates a fundamentally different, advanced technology for tape recording. LGMR offers a unique combination of the best optical and magnetic technologies for dramatically higher capacities through increasing the number of recording tracks on the data-bearing surface of the media.

Pivoting Optical Servo
The Pivoting Optical Servo (POS) is a Quantum invented, optically assisted servo system designed for high-duty-cycle applications. The POS decreases costs and increases user convenience because it eliminates the need to pre-format tape. The Super DLTtape system can use fully 100 percent of the front side of the media for data recording by reading optical servo tracks pre-recorded on the unused reverse side of the media.

Magneto-Resistive Cluster (MRC) Heads
MRCs are a cluster of small, cost-effective Magneto-Resistive (MR) heads densely packed together using advanced thin-film processing technology. They deliver higher data-transfer rates and capacity than traditional MR heads of equal size.

New High-Efficiency PRML Channel
Quantum’s advanced Partial Response Maximum Likelihood (PRML) channel technology was jointly developed with Lucent Technologies, bringing new levels of performance and capacity to high-performance linear tape drives. Advanced PRML provides high encoding efficiency recording densities for greater capacity and performance, which enables SuperDLTtape systems to substantially increase cartridge storage capacity and transfer rates.

Advanced Metal Powder Media
The Super DLTtape system uses state-of-the-art Advanced Metal Powder (AMP) media technology for storing very high densities of data. AMP media consists of four layers including the coated back layer for receiving optical servo tracks. Other advances including a new tape leader buckling mechanism, a rugged tape cartridge receiver and a modular plug-and-play design contribute to long term reliability and data integrity to meet customer backup and archive data storage needs world wide.

3. What is the basis for Super DLTtape technology?
Super DLTtape technology is based on Laser Guided Magnetic Recording (LGMR ™ ) technology. LGMR incorporates a fundamentally different and advanced technology for tape recording. It provides a unique combination of the best of optical and magnetic technologies resulting in dramatically higher capacities by substantially increasing the number of recording tracks on the data-bearing surface of the media. By recording data magnetically on the front side of the tape and tracking optically on the back side, LGMR takes advantage of proven technologies in order to provide the most efficient, reliable and scalable data backup solution to the midrange market.

4. What unique technologies are incorporated in Super DLTtape?
In addition to LGMR, Super DLTtape technology incorporates five unique and highly enabling technologies. All these technologies will be incorporated into the first generation of Super DLTtape technology in order to provide a highly stable, seamless and robust platform.

  • Pivoting Optical Servo (POS) — An optically assisted servo system designed for high duty cycle applications, POS eliminates the need for tape to be preformatted, which decreases cost and increases user convenience. By implementing an optical servo on the unused backside of the media, Super DLTtape technology can utilize 100% of the front side for data recording. This contrasts with traditional magnetic servo tape products (QIC, Magstar, Magstar MP, LTO), in which a portion of the front side of the media must be reserved for servo activity, thus limiting the available space for data recording.
  • Magneto Resistive Cluster Heads (MRC) — A cluster of small, cost effective MR heads densely packed together using advanced thin film processing technology that can deliver higher data transfer rates and capacity than traditional MR heads of equal size.
  • New High Efficiency PRML Channel — Improving on PRML technology traditionally used in disk drives, advanced Partial Response Maximum Likelihood (PRML) channel technology was co-developed with Lucent Technology to bring new levels of performance and capacity to high performance linear tape drives. This provides high encoding efficiency and recording densities for greater capacity and performance and enables Super DLTtape technology to substantially increase transfer rates and capacity.
  • Advanced Metal Powder (AMP) Media — A state-of-the-art media using durable metal powder technology for storing very high densities of data. AMP will include the optical guiding targets on the backside.
  • Positive Engagement — A highly robust tape leader-buckling mechanism for high duty cycle automated environments.

5. What is involved in the new Pivoting Optical Servo (POS) technology, and what is its benefit?
POS combines high density magnetic read/write data recording with laser servo guiding to provide an order of magnitude track count increase over current DLTtape products. The benefits include:

  • No media pre-formatting required
  • No extra read/write head elements required
  • 100% of the tape is now available for data recording
